Hey, cool! Had many throwing stars when I was a kid...well, when I was a ninja. I remember in those days, I used to buy them at gun shows with my dad, also from comic books. Yep, anyone remember that one page in certain comic books that sold weapons like tear gas pistols, machetes, stars, clubs, saps, brass knuckles etc?? I remember buying an 8-pointed star with a big square hole in the middle. Yep, my allowance and can money went to weapons. :P Yeah, I agree, you would think that you would find more of those detecting.
